DW:

Took data with fast treatment plan verification prototype on 21st February.
Data received from Tony Price:
- Spectra look messy with significant energy spread.
- Can see difference between with and without polyethylene sheet.
Everything written up on Wiki: just need to add photos.
To Do:
- Extract PRaVDA tracking data.
- Email Tony Price and check exact energy and find out whether they have any energy spread data.
- Correlate with scintillator pulses.
- Create 3D dose distribution.

JS:

Working on building CAD models of Clatterbridge beamline.
Certain components are not specified correctly or overlap: SJ has provided most up-to-date drawings he has; MH will do the same.
To import models into Geant4:
- Break each model down into constituent parts.
- Create assembly of all components made of the same material.
- Export this model as an STL-File (meshed CAD model).
- Convert each material STL-File into GDML.
- Import this meshed GDML file into Geant4 as given material.
To Do:
- Finish CAD model for MH's simulation.
- Define vacuum for initial vacuum tube.
- Rerun simulations to check differences in simulations with CAD components.

LK:

Finished 3D printed cover for bridge over ISDI sensor bond wires.
To Do:
- Install software on DAQ PC: DSLR software, EPIX card drivers and software, LabView, Aspect software (once we have it).
- Test sensor.

ABF:

Scintillator sheets now polished: most of the scratches now removed.
To Do:
- Install software on DAQ PC: Caen digitiser and HV.
- Packing inventory.

MH:
